Definitions

  • the present invention generally relates to a locking device and more particularly, to a steering shaft locking device for use in a motor vehicle and the like, which is provided mainly for the purpose of theft prevention of the motor vehicle.
  • an engaging member which is arranged to be engageable with an engaging slot formed in one face of a lock member in response to insertion of a key into a rotary member of a cylinder lock and to be projectable into the engaging slot by an urging force of a spring.
  • the lock member is engaged with or projectable for its engagement with a steering shaft at a "Lock” position of the lock member, whereby the lock member is retracted in response to rotation of the rotary member in the direction toward an "On" position of the rotary member through the key so that the engaging member projectable into the engaging slot may be fitted into the engaging slot through a probeable operation of the engaging member.
  • an essential object of the present invention is to provide an improved steering shaft locking device for use in a motor vehicle and the like, which is simple in structure, with substantial elimination of the disadvantages inherent in conventional steering shaft locking devices of this kind.
  • Another important object of the present invention is to provide an improved steering shaft locking device of the above-described type which is highly reliable in actual use and suitable for mass production at low cost.
  • an improved steering shaft locking device for use in a motor vehicle and the like, including a sleeve formed with an aperture, in which a steering shaft is rotatably accommodated, and a housing accommodating a cylinder lock, a lock member, etc. therein so that said lock member may be projectable for its engagement with said steering shaft in response to rotation of a rotary member of said cylinder lock in the direction toward a "Lock" position of said rotary member.
  • the steering shaft locking device comprises:
  • a rotary ring formed with an opening and a boss portion, which is rotatably provided inside said sleeve so as to enclose an outer circumference of said steering shaft at a position of projection of said lock member into said sleeve and at a position of its retraction from said sleeve;
  • said lock member being selectively prevented from being projected into said steering shaft through said opening so as to unlock said steering shaft, and being projected into said steering shaft through said opening so as to lock said steering shaft when said rotary member is disposed at a regular angular position and a rotational angular position, respectively;
  • a wire connected, at one end thereof, with said boss portion and connected, at the other end, either with a seat of said motor vehicle, whose top face is caused to selectively move downwards and upwards when a driver takes said seat and leaves said seat, respectively, or with a door etc. of said motor vehicle, arranged to be opened and closed;
  • said rotary ring is rotated from the regular angular position to the rotational angular position through said wire against the urging force of said spring so that said lock member may be projected into said steering shaft through said opening of said rotary member so as to lock said steering shaft.
  • the rotary ring is rotatably provided, only through a partial modification of the sleeve, in the sleeve so that the opening of the rotary ring may be displaced from the lock member so as to unlock the steering shaft at the regular angular position of the rotary member with the steering shaft being rotatably accommodated in the sleeve, whereby the steering shaft locking device has been made simple in structure, highly reliable in actual use, and suitable for mass production at low cost.
  • FIG. 1 is a cross-sectional view of a steering shaft locking device for use in a motor vehicle and the like according to one preferred embodiment of the present invention
  • FIG. 2 is a side sectional view taken along the line II--II in FIG. 1,
  • FIG. 3 is a side elevational view as observed in the direction of the arrow III in FIG. 1,
  • FIG. 5 is a side sectional view taken along the line V--V in FIG. 4,
  • FIG. 6 is a front elevational view partly in section of a seat of the motor vehicle, with which one end of a wire of the steering shaft locking device of FIG. 1 may be connected, and
  • FIG. 7 is a top plan view of a door of the motor vehicle, with which one end of the wire may be connected.
  • FIGS. 1 and 2 a casing 1 of a steering shaft locking device for use in a motor vehicle and the like according to one preferred embodiment of the present invention, formed, for example, by plastic molding or die casting, including a sleeve 2 in which a steering shaft a is rotatably accommodated, and a housing 3 which intersects with the sleeve 2.
  • the sleeve 2 is formed with an aperture 4 and an arm 8.
  • a rotary ring 5 in which the steering shaft a is loosely provided is rotatably fitted into the sleeve 2 and is formed with an opening 6.
  • the rotary ring 5 is further formed with a boss portion 7 projecting upwards out of the sleeve 2 through the aperture 4 of the sleeve 2.
  • a spring 9 is connected, at one end thereof, with the boss portion 7 of the rotary ring 5 and connected, at the other end, with the arm 8 of the sleeve 2 so that the boss portion 7 may be brought into contact with one side of the aperture 4 so as to dispose the rotary ring 5 at a regular angular position for unlocking the steering shaft a.
  • a wire 10 is connected, at one end thereof, with the boss portion 7 of the rotary ring 5.
  • the housing 3 accommodates therein, in a known manner, a cylinder lock 11 having a stationary member 12 into which a rotary member 13 is fitted, with a key 19 being inserted into the rotary member 13, a second rotary member 15 in association with a square projection 14 of the rotary member 13, an ignition switch 16 for rotating a movable contact holder through the second rotary member 15, and a lock member 17 which is controlled by the second rotary member 15 so as to be selectively projected into the sleeve 2 through the opening 6 of the rotary ring 5 by an urging force of a compression spring 18 and to be retracted from the sleeve 2.
  • the lock member 17 is selectively prevented from being projected into the steering shaft a through the opening 6 so as to unlock the steering shaft a, and is projected into the steering shaft a through the opening 6 so as to lock the steering shaft a when the rotary ring 5 is disposed at the regular angular position shown in FIGS. 1 and 2, and the rotational angular position shown in FIGS. 4 and 5, respectively.
  • the wire 10 is connected with the door 25, as shown in FIG. 7, the wire 10 is connected with the door 25 through guide rollers 26 and 27, etc., whereby, when the door 25 is opened, the rotary ring 5 is rotated from the regular angular position shown in FIG. 1 to the rotational angular position shown in FIG. 4 through traction of the wire 10.
  • the rotary ring 5 is rotated from the regular angular position to the rotational angular position by the wire 10 through the boss portion 7 so that the lock member 17 may be projected into the steering shaft a through the opening 6 of the rotary ring 5.
  • Mounting of the rotary ring 5 can be effected through a slight modification of the sleeve 2.
  • the steering shaft locking device can be made simple in structure. Furthermore, in accordance with the present invention, the lock member 17 is prevented from being projected into the sleeve 2 so as to unlock the steering shaft a so that free steering of the motor vehicle can be affected until the seat occupant leaves the seat 21 or opens the door 25, etc. even if the key 19 is withdrawn from the rotary member 13 of the cylinder lock 11 after the rotary member 13 has been rotated to the "Lock" position (4).
